DETAILED DESCRIPTION

FIG. 1 shows a piece of lighted tubing 100 according to an embodiment. The lighted tubing 100 includes a light source 110 and tubing 120 having an elongate wall 122 defining an interior channel 124 for transporting a substance. The tubing 120 is preferably medical tubing, i.e., oxygen tubing. While the tubing 120 is not limited to oxygen tubing, the tubing 120 is preferably a highly inert and flexible sterile tubing for medical use. The tubing 120 may present a circular cross-section 125 or a cross-section 125 having another shape, such as oval or oblong, for example. The light source 110 allows the tubing 120 to be seen in the dark, preventing accidents caused by tripping over, dislodging, or completely disconnecting unlit tubing 120.

The light source 110 is shown in FIG. 1 as a chemical coating 110 a having glow-in-the-dark characteristics. Numerous phosphorescent paints 110 a found in the marketplace today would be appropriate. After exposure to incident radiation (light), some of these coatings 110 a may emit light for up to twelve hours that can be seen by humans. Further, according to their manufacturers, some of these phosphorescent paints 110 a can be charged millions of times and have a lifespan of over twenty years. These coatings 110 a can be obtained in various colors, and may be nearly transparent in lit surroundings.

As shown in FIGS. 2 and 3, the light source 110 may include a piece of tape 110 b having glow-in-the-dark characteristics. The tape 110 b may have adhesive 111 attaching the tape 110 b to the wall 122 (FIG. 2), or the tape may be a vinyl tape 110 b capable of being selectively affixed to the wall 122 through an electrostatic interaction (FIG. 3). If the tape 110 b includes the adhesive 111, the tape 110 b may be constructed of any of a variety of materials, including cloth, plastic, metal, paper, and others. The tape 110 b may be manufactured from a material having glow-in-the-dark characteristics, or glow-in-the-dark characteristics may be added to the tape 110 b, such as by adding the chemical coating 110 a discussed above to the tape 110 b.

As shown in FIG. 4, the light source 110 may include a heat-shrink material 110 c having glow-in-the-dark characteristics. Somewhat similar heat-shrink materials are currently used with electrical cords. The heat-shrink material may be manufactured from a material having glow-in-the-dark characteristics, or glow-in-the-dark characteristics may be added to the heat-shrink material. Portion 112 a represents the heat-shrink material 110 c in an initial state, and portion 112 b represents the heat-shrink material 110 c after heat has been added.

FIGS. 5 and 6 show a light source 110 that includes a ruminator 113, i.e., a LED or a light bulb. The luminator 113 is preferably a LED due to the negligible amount of heat produced by a LED, though other luminators 113 may be used. The ruminator 113 is operatively connected to a clip 114. The clip 114 shown in FIGS. 5 through 9 is a sleeve 114 a having an inner diameter 115 that is larger than an outer diameter of the elongate wall 122. The sleeve 114 a presents first and second ends 116 a, 116 b, and an opening 116 c extends from the first end 116 a to the second end 116 b to allow the sleeve 114 a to be selectively positioned about the wall 122, as shown in FIGS. 7 a through 8 b. As shown in FIGS. 5, 7 a, and 7 b, the sleeve 114 a may include a respective flange 116 d extending outwardly from each side of the sleeve opening 116 c so that a user may easily enlarge the sleeve opening 116 c and selectively position the sleeve 114 a about the wall 122. Though not shown, the ruminator 113 is in communication with a power source (i.e., a battery). Also, the ruminator 113 may be constantly emitting light, or a user interface (i.e., a switch) may be in communication with the ruminator 113 to allow the ruminator 113 to selectively emit light.

FIGS. 7 a through 8 b show a light source 110 without a ruminator 113. Instead, the sleeve 114 a includes glow-in-the-dark characteristics. The sleeve 114 a may be manufactured from a material having glow-in-the-dark characteristics, or glow-in-the-dark characteristics may be added to the sleeve 114 a, such as by adding the chemical coating 110 a discussed above to the sleeve 114 a. FIGS. 7 a and 8 a show that a plurality of sleeves 114 a may be operatively attached to the wall 122. The sleeves 114 a may be positioned periodically along substantially the entire length of the wall 122 so the location of the entire wall 122 may be observed in the dark. Alternately, one or more sleeve 114 a may be positioned along a predetermined portion of the wall 122 so that the predetermined portion may be observed in the dark.

FIG. 9 shows a light source 110 that includes a ruminator 113. A conductor 117 preferably conducts light produced by the ruminator 113, further marking the position of the wall 122. The conductor 117 may also connect the luminators 113 to one another, forming a chain of luminators 113. The conductor 117 is preferably flexible and may be constructed of a fiberoptic bundle.

FIGS. 10 and 11 show a conductor 117 positioned inside the tubing interior channel 124 (FIG. 10) and positioned inside the tubing wall 122 (FIG. 11). A ruminator 113 (not shown) introduces light into the conductors 117, and the conductors 117 conduct and transmit that light. This effectively displays the position of the wall 122.

FIGS. 12 through 15 show a clip 114 that is a hook apparatus 130 for selectively attaching the ruminator 113 to the wall 122. The hook apparatus 130 preferably houses a power source 140 (i.e., a battery) in communication with the ruminator 113, and as seen in FIGS. 12 through 15, the ruminator 113 may protrude from the hook apparatus 130. Alternately, the ruminator 113 may be located inside the hook apparatus 130 as long as the hook apparatus is transparent or includes openings to allow light from the ruminator 113 to escape. The hook apparatus 130 may include inner and outer portions 132, 134 capable of sliding along one another to alter the hook apparatus 130 between an open configuration 130 a (FIGS. 12 and 14) and a closed configuration 130 b (FIGS. 13 and 15). A hook 131 may be attached to the inner portion 132 for selectively connecting the inner portion 132 to the wall 122. A biasing element 136 (i.e., a spring or tension cord) is preferably in communication with the inner and outer portions 132, 134 to bias the hook apparatus 130 toward the closed configuration 130 b. The outer portion 134 may define a recessed region 135 adjacent a top end 134 a so that the wall 122 may be located at least partially inside the hook apparatus 130 when the hook apparatus 130 is attached to the wall 122 and the hook apparatus 130 is at the closed configuration 130 b. The inner and outer portions 132, 134 preferably include interfering protrusions 132 a, 134 a so that the inner and outer portions 132, 134 are restricted in their range of motion. The interaction between the protrusions 132 a, 134 a keeps the wall 122 from being kinked or damaged by the outer portion 134 or the hook 131.

An example of use for the hook apparatus 130 (FIGS. 12-15) is as follows. The hook apparatus 130 is initially at the closed configuration 130 b (FIG. 13) due to the biasing element 136. Opposing ends of the inner and outer portions 132, 134 may be squeezed together, altering the hook apparatus 130 to the open configuration 130 a (FIG. 14). The hook 131 may then be placed about the wall 122 (FIG. 12). By releasing the opposing ends of the inner and outer portions 132, 134, the hook apparatus 130 returns to the closed configuration 130 b (FIG. 13) due to the biasing element 136, removably attaching the hook apparatus 130 to the wall 122.

As shown in FIGS. 2 and 3, the light source 110 may define indicia 119. The indicia 119 may provide information pertaining to the medical use of the tubing 120 (FIG. 3, for example), the direction of flow for a substance inside the tubing 120 (FIG. 2, for example), manufacturer information, or other relevant subjects. By indicating direction of flow, the indicia 119 also makes it very easy to observe and identify coils or kinks in the tubing 120. The indicia 119 may alternately provide comforting or emotionally-beneficial markings, such as teddy bears, snowflakes, etc. Such markings may be especially comforting to a child, though they are not solely intended for use with children. The indicia 119 as shown in FIGS. 2 and 3 may include the glow-in-the-dark characteristics discussed above, or the indicia 119 as shown in FIGS. 2 and 3 may be viewable because of a lack of glow-in-the-dark characteristics. Importantly, contrast between the characteristics of the indicia 119 and the surrounding area define the indicia 119. Though only shown in FIGS. 2 and 3, the indicia 119 can be used for any of the described embodiments. For embodiments incorporating luminators 113, a cover lens having indicia-defining light passageways may be placed adjacent the luminators 113 to define the indicia 119 with the light produced by the luminators 113.
